辽宁科技大学本科生毕业设计(论文) 第V页 厚板轧机设计摘要随着中厚板在造船、建筑、国防、军事等领域的广泛应用，厚板轧制技术在工业领域的重要性日益突出。本次设计就是从生产实际出发，通过下厂实践、调研、查阅大量资料，了解了中厚板生产工艺及国内外发展现状，特别对厚板轧机的组成和结构有了深入了解和认识。本设计的厚板轧机是以2350厚板轧机为基础进行设计。首先根据轧钢机械的设计方法，从工作辊与支承辊的设计计算开始，对厚板轧机的传动系统进行了设计。然后通过轧制力矩的计算推算出主传动电机的功率，并且对所选的电机进行过载和发热校核。同时还对机架、压下系统进行了设计和校核，最后考虑经济和环保的要求进行了分析评价。关键词：厚板轧机；传动系统；工作辊；设计计算；机架Plate Mill DesignAbstractWith the wide application of plate in shipbuilding, construction, defense and military fields, Plate rolling technology have become increasingly importance in the industrial area. The production design is from the actual conditions of the country, understand the plate production process and the development of the status quo at home and abroad, especially have a deeper understanding and awareness for the composition and structure of thick plate rolling mill, by the practice of factory, research, access to large amounts of data. The design of the plate mill is based on 2,350 design. First, design and calculate the work roll and back-up roll and devise the drive system of plate mill in accordance with the design method of rolling mill machinery. Then, calculate the main drive motor power through the rolling moment calculation, and make the load and heat checking to the motor of selected. At the same time also design and check the rack and the system of press. Finally consider the economic and environmental requirements for the analysis and evaluation.Keywords : Plate Mill; Transmission; Work Roll; Design; rack目 录摘要Abstract1、绪论11.1、选题背景11.2、中厚板轧机简介及产品11.3、中厚板轧机原料及生产流程21.4、中厚板轧机发展历史及发展趋势 21.5、研究内容和研究方法 32、传动方案评述与选择42.1、方案选择42.2、方案评述52.3、电机选择52.4、连接轴选择52.5、轧辊轴承选择 53、轧制力能参数的计算63.1、轧制力的计算 63.1.1、轧制规程63.1.2、轧辊主要尺寸的选择63.1.3、轧制力的计算73.2、轧辊力矩的计算104、主电机容量选择 144.1、初选电机 144.2、主电机力矩 144.3、计算各轧制阶段时间计算 174.4、电机的校核 185、轧辊计算及强度校核205.1、工作辊强度校核205.2、支承辊强度校核205.3、工作辊与支承辊间的接触应力校核226、机架的设计校核 256.1、机架结构参数选择256.2、机架的强度计算266.2.1、受力分析266.2.2、弯矩计算266.3、机架强度校核297、 压下系统计算3
